Application June9, -19 54,'Serial No. 435,529 1 0mm. cl. 215-71) This invention relates generally .to vessel closures .but more specifically .to-an EHFilCUlaKfiLCIOSlJI B havinga springbiased movable-portion which isnormallytin forced closed position and which has handtqperable means for overcoming said spring force -.to-maintain said portion in open position for gpouring or spilling the vessel .contents.

Themain feature -of the invention resides .in the pro- .vision of a closure or cover havin S ructure permitting the removal vof the contents of the vessel by push button action without removing full cover, "the release :of finger pressure on said button causing an automatic closure of the movable portion of the cover.

A feature of the inventionresidesdn the provision of a closure for vessels wherein repetitive .use of the contents is made :and which is sanitary'in use, cannot be misplaced and lost and which reduces time and .efiort by elimination of application and removal pf the .cover for the Theme, commercial establishment and particularly in pharmacies Where compounding of prescriptions necessitate the repeatedause .of .ingredientsiin particular bottles.

.A further feature of the inventionresides inttheiprovision o'f-.a vessel cover structure whichhasbeenapplied to arbottlemr other vessel inthemormal way as bythreaded engagement at the'filling plant, but which for operation either at home, in the laboratory or in the retail establishment is made to function without cover removal after first removing a sealing disc placed on the underside of A nited States Patent 1 the top wall of the cover prior to closure at the filling plant.

Other objects of the invention reside in the economy of production, long life, sanitation and ease of operation of the device.

These objects and other incidental ends and advantages of the invention will hereinafter appear in the progress of the disclosure and as pointed out in the appended claim.

Accompanying this specification are drawings showing a preferred form of the invention wherein:

Figure 6 is an enlarged sectional view of Figure 5 across the plane 66 thereof.

Figure 7 is an exploded view in perspective showing the disassembled parts of the cover.

In accordance with the invention and in accordance with the preferred form shown, numeral 10 indicates a conventional bottle or vessel having a neck 11 provided with an external thread 12. The bottle, as shown, is also 2,828,042 Pptentecl Mar. 25, 1958 .2 provided with a conventional bead 13 between the neck and body portions.

Vessel It) may be of glass, composition or other suitable material designed to hold contents either in fluid, powder, tablet or other form while the cover, generally designated by numeral 14, is comprised of a cylindrical section having a composite top wall an opening on the composite bottom, and an internal thread on the composite side wall to engage the external thread 12 of the bottle neck 11. i

'As shown, the cylindrically formed composite cover generally designated by numeral 14 consists of two cover components generally designated 15 and .16 ,and'whigh when in engagement form the articulated closure cover 14. i

The cover component 15 consists of a split section which is smaller than the diametric section of the complete closure cover while component 16 larger in diametric section completes the cylindrical section as best shown in Figure 7.

Component 15 has a top wall segment 17 provided with a side Wall segment 18, the latter having the inner side provided with an internal or female thread segment '19. Component 15 further has a top wall free straight edge 20 .and side wall free edges 21 and 22. Extending from the free edge 20 and paralleland intermediate the length thereof is a pinion 23 integrally secured and projecting therefrom and having an axial pin-receiving orifice 2.4 therethrough. Behind pinion 23 .and centrally disposed of top Wall 17 is a recessed portion 25 to provide clearance for the component 15 when it is in raised position as willhereinafter appear.

The other component 1-6 of the cover similarly has a top .wall segment 26 anda side wall segment 27 with an internal or female thread segment 28 on the inner side. Top wall segment 26 is provided with a central notch 29 for admission of a pinion 23 .and has a pin.- receiving orifice 30 in alignment with the pinion orifice 24 whereby the components 15 and 16 are pivotally secured together as by means of the pin 31 adapted to enter said orifices 24 and 30. Notch 29 terminates inwardly in a cylindrical wall section 32 while the top Wall segment is provided with a curved ridge 33 adjacent the upper edge of 32.

Wall section 32 is adapted to slidably receive a rack '35 engagable with pinion 23. Rack 35 has a top button portion 36 and is further in the form of a partial cylinder to conform with Wall 32 and has straight teeth 37 along a fiat wall portion. A bottom lug 38 centrally disposed on the partial cylindrical portion of rack 35 is adapted to recess in and be stopped by a bottom notch 34 on wall 32. The rack 35 is normally urged upwardly for normal closing position of component 15 by a coil spring 39 mounted between the shoulder 32a of wall 32 and the underside of rack button 32.

The parts are easily assembled by first introducing rack 35 into component 16 and having one end of spring 39 disposed on the underside of rack button 36 and the other spring end disposed on shoulder 32a with lug 38 in recess 34. Thereafter component 15 is introduced into the notch 29 so that the teeth of pinion 23 are engaged to the teeth of rack 37. At this time, orifices 24 and 30 are in alignment permitting pin 31 to be therein introduced to pivotally secure the parts 15 and 16 together. The force of spring 39 is sufiicient to normally maintain rack 35 in uppermost and stopped position to maintain component 15 in closed position.

At the filling plant, a sealing disc 40 is introduced on the inner side of the component top walls 17 and 26 and the cover is then ready to be screwed on to neck 11 of the receptacle.

When the composite cover is to be used following the filling operation, the sealing member 40 is first removed. Thereafter, to open component 15, it is merely necessary to press button 36 of the rack downwardly against the force of spring 39 and in so doing pinion 23 secured to component 15 is caused to turn about pin' 31 to a maximum position defined by the abutment of lug 38 against the top wall of notch 34. The turning of pinion 23 carries component 15 to a 90 degree position as shown in FiguresS and 6 and button 36 clears top wall 17 by means of recess 25 therein. The bottle is then ready to have contents such as tablets 41 or fluid 42 ejected on release of finger pressure on button 36, component 15 is forced back by spring 39 for closing position or reengagement with the neck thread portion 12.

' It is to be noted that the cover is capable of being removed as the ordinary cover if it is desired not to utilize the rack and pinion assembly. Furthermore, it is to be realized that it is not necessary to have the closure cap in the form of a threaded device but the cap as a whole may engage the neck of the vessel in a frictional manner and the invention may be applicable thereto just as Well.

The closure described although having particular advantage in the prescription department of a drugstore may also be used in the laboratory, retail establishments, in the home and wherever and whenever a cap is required for a bottle which requires constant and repetitious use.

The closure may be made of any suitable material such as glass, composition and plastic, and the rack and pinion may also be made of the same material. The spring is preferred to be of steel and coated with an inert material to eliminate possibility of corrosion while the pin may also be coated for the same purpose.

In connection with sealing member 40, there need be no necessity for removal prior to operation as has been mentioned. Member 40 may be provided with a central flap hingeable on a score line 43 and capable of being depressed downwardly against a perforation 44 severable by downward movement of rack 35 as shown in Figure 7. Moreover, another hinge line may be scored on mem- 4' her as at 54 so that the portion under cover component 15 can be raised when contents of the vessel are to be removed and lowered and closed by the downward movement of the cover component.

I wish it understood that minor changes and variations in the material, integration, location and size of parts may all be resorted to without departing from the spirit of the invention and the scope of the appended claim.

We claim:

A removable coverfor bottles and other vessels comprising a cylindrically shaped internally threaded body having a top wall and adapted for threadedengagement with the bottle neck, said body and top wall having two abutting sections and an axle joining said sections in pivoted engagement, a fixed pinion extending 05 the top wall abutting edge'of one of said sections, the other section having a pair of communicating recesses in the top wall and extending from the abutting edge thereof, the first of said recesses receiving said fixed pinion, anda spring-urged pinion-engaging rack slidably mounted between said fixed pinion and the second of said recesses and limiting stop means between said rack and said other section for movement of said rack whereby the section carrying the pinion is raised by depressing said rack to free said section of engagement with the bottle neck for pouring purposes and whereby on release of said rack, said section is forced into closing position.
